The purpose of this study is to compare the overall survival in patients with previously untreated metastatic pancreatic cancer receiving gemcitabine/nab-paclitaxel plus OGX-427 or gemcitabine/nab-paclitaxel plus placebo.

Three loading doses of OGX-427 at 600mg IV will be administered Days -9 to -1. Following the loading dose period, OGX-427 will be administered at 600mg IV weekly Days 1, 8, 15, and 22 of each 28 day cycle during the Treatment Phase.

Drug: OGX-427

Three separate administrations of OGX-427 will be given during the 9-day Loading Dose Period. Following the Loading Dose Period, patients will receive 600mg OGX-427 prior to the administration of nab-paclitaxel (125mg/m2 IV)and gemcitabine (1000mg/m2 IV)administration on Day 1, 8, and 15 of each cycle. OGX-427 will also be administered on Day 22 during each cycle (i.e., weekly). Patients will continue 28 day treatment cycles until disease progression or until other reasons for discontinuation from treatment.

Placebo Comparator: Placebo

Three loading doses of placebo will be administered Days -9 to -1. Following the loading dose period, placebo will be administered weekly Days 1, 8, 15, and 22 of each 28 day cycle.

Drug: Placebo

Three separate administrations of Placebo will be given during the 9-day Loading Dose Period. Following the Loading Dose Period, patients will receive placebo prior to the administration of nab-paclitaxel (125mg/m2 IV)and gemcitabine (1000mg/m2 IV)administration on Day 1, 8, and 15 of each cycle. Placebo will also be administered on Day 22 during each cycle (i.e., weekly). Patients will continue 28 day treatment cycles until disease progression or until other reasons for discontinuation from treatment.

Detailed Description:

Patients with pancreatic cancer usually present with inoperable disease and systemic therapy becomes the primary form of treatment. The combination of gemcitabine plus nab-paclitaxel represents an appropriate front-line standard of care for patients with metastatic pancreatic cancer. However, poor outcomes with this disease warrant exploration of novel drugs with unique mechanisms of action. Preclinical evidence suggests that OGX-427 has shown promising activity in pancreatic cancer. In this trial, we will compare the overall survival of patients with previously untreated metastatic pancreatic cancer using OGX-427 with either gemcitabine/nab-paclitaxel or a placebo with gemcitabine/nab-paclitaxel.

Criteria

Inclusion Criteria:

Histologically- or cytologically confirmed pancreatic adenocarcinoma

Stage IV disease (measurable disease NOT required)

Eastern Cooperative Oncology Group (ECOG) performance score of 0-1

At least 18 years of age

Female patients who are not of child-bearing potential, and fertile female patients of child-bearing potential who agree to use adequate contraceptive measures, who are not breastfeeding, and who have a negative serum or urine pregnancy test within 72 hours prior to start of randomization.

Fertile male patients willing to use adequate contraceptive measures.

Adequate bone marrow, renal, and hepatic function.

Ability to understand the nature of this study protocol, comply with study and/or follow-up procedures, and give written informed consent

Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.

Exclusion Criteria:

Any prior systemic or investigational therapy for metastatic pancreatic cancer. Systemic therapy administered alone or in combination with radiation in the adjuvant or neoadjuvant setting is permissible as long as it was completed > 6 months prior to the time of study randomization.

History of other diseases, metabolic dysfunction, physical examination findings, or clinical laboratory findings giving reasonable suspicion of a disease or condition that, in the opinion of the investigator, renders the subject at high risk from treatment complications or might affect the interpretation of the results of the study.

Presence of known central nervous system or brain metastases.

Known human immunodeficiency virus (HIV) infection.

Active second invasive malignancy (except non-melanomatous skin cancer), defined as any malignancy with current need for cancer therapy or high possibility (>30%) of recurrence during the study.

Major surgery within 4 weeks of the start of study treatment (defined as those surgeries that require general anesthesia. Insertion of a vascular access device is NOT considered major surgery.). Patients must have recovered from the side effects of any major surgery prior to randomization.
